The Dark Zone is the player-versus-player competitive multiplayer mode featured in The Division, where a lot of high-end weapons are left behind when the military retreats in the game. It is separated from the main campaign and has its own progression system. These people, however, can turn against the player at any moment, going rogue.
On Black Friday 2015, a smallpox epidemic, transmitted by a virus planted on banknotes, sweeps through New York City. The disease, known as “Green Poison” or “The Dollar Flu”, causes widespread chaos, and Manhattan is placed under quarantine. The U.S. Government activates sleeper agents in the population who operate for the Strategic Homeland Division, or simply “the Division”, to assist emergency responders, now called the Joint Task Force (JTF), in restoring order. In Brooklyn, the protagonist, a Division agent, assists the JTF before planning to depart for the Quarantine zone with fellow agent Faye Lau.
